<p>The Change Function Usage Information (OPM, QSYCHFUI; ILE,
QsyChangeFunctionUsageInfo) API changes the usage information for a function.
The usage information for a function indicates which user profiles are allowed
or not allowed to use a function.</p>
<p>The usage information is stored with the user profile. To save and restore
the usage information, you must use the same methods as with other user profile
information (Save Security Data (SAVSECDTA) command, Restore User Profiles
(RSTUSRPRF) command, Restore Authority (RSTAUT) command).</p>
